while performance-based language assessment has led to an increased authenticity and content validity in the practice of writing assessment, the reliability of ratings has become a major issue. research findings have shown different reactions by native english speaker (nes) and non-native english speaker (nns) teachers to students’ writings. the focus of this study is on investigating whether i...
Historically, about half the oil transported through the global marine environment has come through the Arabian Gulf and the annual input of oil to the gulf’s marine environment is skewed toward sources connected with marine transport. As a case study, we assess the damages from an oil spill caused by a collision between the crude oil tankers Baynuna and the Seki on 30 March 1994. The collision...

United States fisheries are managed by regional councils. Fishermen can participate in fisheries managed by multiple councils, and effort controls in one region could lead to effort leakage into another. Using difference-in-differences, we test for leakage across regional fisheries boundaries for a catch share program in New England. We find evidence that the New England groundfish sector progr...
Fisheries data assembled by the Food and Agriculture Organization (FAO) suggest that global marine fisheries catches increased to 86 million tonnes in 1996, then slightly declined. Here, using a decade-long multinational 'catch reconstruction' project covering the Exclusive Economic Zones of the world's maritime countries and the High Seas from 1950 to 2010, and accounting for all fisheries, we...
Failures in fisheries management have been linked to our inability to embrace the inherent uncertainty of fisheries systems. Fisheries decisions should be made on the basis of integrated evaluations of strategy alternatives, where comparisons of comprehensive scenarios incorporate strategic biological and socio-economic objectives and constraints, and explicitly take account of system uncertain...
Recent reports suggest that most of the world's commercial fisheries could collapse within decades. Although poor fisheries governance is often implicated, evaluation of solutions remains rare. Bioeconomic theory and case studies suggest that rights-based catch shares can provide individual incentives for sustainable harvest that is less prone to collapse. To test whether catch-share fishery re...
Policy efforts to reduce fisheries impact have often created micro-management. Detailed regulations are restricting the fishing industry, and are also acknowledged to limit the progress towards sustainable management. Industry representatives, political bodies and scientists have therefore argued for more simplicity and transparency. Here, fisheries management is quantified in terms of trends i...
